Ultrastructural features of the human frontal cortex neurons of maturing and hydrocephalic cerebrum.
Human frontal cortex neurons of hydrocephalic infants were studied with electron microscope. A number of maturing neurones exhibited shrinkage and increased electron density of cytoplasmic matrix in the midst of gross hydrocephalic interstitial oedema. Remarkable preservation of growth cones and arrays of microtubules in a few neuronal perikarya and axons were discernible. Rows of normal looking neurones with parallel arrays of cisternae of rough endoplasmic reticulum were also detected. Thus, preservation of significant number of neurones was apparent even in cases of extreme hydrocephalus.
